GT74LVC2T45V8 from GTIC, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCCA power_in A-port supply voltage, specified for 1.65V ≤ VCCA ≤ 5.5 V.
2 A1 bidirectional Input/output A1, referenced to VCCA.
3 A2 bidirectional Input/output A2, referenced to VCCA.
4 GND power_in Ground.
5 DIR input Direction control signal: high selects A-to-B transmission and low selects B-to-A transmission; DIR is supplied by VCCA.
6 B2 bidirectional Input/output B2, referenced to VCCB.
7 B1 bidirectional Input/output B1, referenced to VCCB.
8 VCCB power_in B-port supply voltage, specified for 1.65V ≤ VCCB ≤ 5.5 V.
